Abstract: The work is preparation of biological active peptide from fresh silkworm chrysalis. After degreasing ,the protein of silkworm chrysalis was enzymolysis by trypsin. The enzymolysis condition is trypsin 0.5%, temperature 50℃, 5h. Biological active peptide be preparation from enzymolysis liquid with method of ultrafiltration. Using microorganism model as it makes, the biological active peptide be detected, which promote glycolysis.

Key words: silkworm chrysalis, biological active peptide, enzymolysis, ultrafiltration
